CENTRIF'UGAL CLOTH ES-DRYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 724,250, dated March 31, 1903.

Application filed May 9, 1902. Serial No. 106,648. (No model.)

1'0 all whom it may concern:

Be it known that I, FREDERICK J os. BIRD, a citizen of theUnited States,residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Centrifugal Separators, of which the following is a specification, reference being had therein to the accompanying drawings,

My invention relates to new and useful improvements in centrifugal machines for extracting moisture from clothes and similar articles; and its object, among other things, is to provide an inexpensive device of simple, compact, and durable construction which is readily set up and operated and into and from which the articles to be dried can be quickly placed andremoved.

With the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is a central vertical section through the machine; and Fig. 2 is a section on lin 2 2, Fig. 1.

Referring to the figures by numerals of reference, l is a circular base having a concentric head 2 thereon at a desired distance from the edge and provided at the center of the top witha recessed bearing-plate 3. A sheetmetal casing 4. is mounted on the base and is prevented from moving laterally thereon by the bead 2. The upper edge of this drum fits within a circular bead 5, formed upon the lower surface of a ring 6, and rods 7 connect the edges of the base and rin'gand serve to clamp the cylinder in position therebetween. Nuts 8 are arranged upon the rods for drawing the parts together. A metal strip 9 is mounted on the ring 6 and extends across the center thereof. This strip is provided at one side of the center with standards 10, connected by a U -shaped bead or rib 11. A box 12 is located 'at the upper end of each standard and serves as a bearing for a horizontal shaft13,havingsuitable driving means, as a crank 1-1, at one end and a beveled gear preferably formed of galvanized wire.

the shaft 17 does not pass through the drum 15 at the opposite end. This gear meshes with a small pinion 16, secured upon a small vertical shaft 17, journaled in the center of the cross-strip 9. Downward movement of this shaft is prevented by the end of the pinion bearing upon the end of a box 18, arranged within the cross-strip and inclosing the shaft. The lower end of shaft 17 is angular, as shown at 19, and engages an angular aperture formed in the center of a cross-strip 20. This strip is bolted upon opposite sides of a ring 21, arranged at the upper edge of a cylinder 22, The lower ends of the casing are fastened in a similar manner upon a base 23, and rods 24 connect the base to a strip 20 and serve to hold them spaced apart and prevent twisting of the wire cylinder. A plate 25 is secured to the under surface of base 23, at the center thereof, and is provided with a conical stud 26, which fits within the recess in plate 3 and forms a bearing for the wire casing or drum 22.

In operation wet fabrics are placed within the casing 22, and the same is then revolved by means of the gearing. The fabrics will be thrown by centrifugal force outward against the netting, and air will be drawn down into the casing and out through the clothes and netting, carrying the moisture therewith. As

8o 22, there is nothing to prevent the fabrics from being promptly thrown against the netting.

I Having thus fully'described my invention, what I therefore claim as new, and desire to secure by Letters Patent, is

1. In an apparatus of the character described the combination with a casing, a base- 1 plate having a head on its upper surface,a ring with a bead on its lower surface, the casing being mounted on the base-plate and ring so as to abut against the beads,a strip'mounted on the ring and extending across the casing, of the rods detachably connected to the base, ring and strip and nuts on said rod'to clamp 5 the casing between the base-plate and ring and also against the beads, substantially as specified.

2. In an apparatus of the character described the combination with the casing, of a reticulated drum rotatably mounted in the casing so as to operate said drum, substancasing having rings at its upper and lower tially as specified. IO portions, a base-plate, a cross-strip extend- In testimony whereof I affix my signature ing across the top of the drum and means for in presence of two Witnesses.
